Loan with No Payment Details

KyleJ

I have two loans in Quicken Classic, both with the same financial institution and both taken out at roughly the same time. When I click on the payment details tab for one of the loans, I see a full list of the payments that have been made to this loan (details blurred to protect my privacy, but you can see that there's a list there):

When I go to the same spot on the other list, it shows no payments despite the fact that payments have been made:

Has anyone seen this?

That's because the 2nd loan was activated for transaction downloading.
At least in Quicken for Windows, an online-connected loan or mortgage account does NOT have a transaction register. All data shown in the account come from whatever information the bank downloads to you ... if this process works at all.

As a result of being connected, the scheduled payment transaction reminder cannot transfer the amount of principal paid into the (non existent) account register and must use a category, usually something like Loan:Principal, instead. The category name seems to vary with the Loan Type you selected when creating the loan account in Quicken.

Effective with Quicken Windows 2018 and newer
you should be able to deactivate an online-connected loan account and regain full control over your transaction register. And you should also review the Scheduled Reminder (or Memorized Payee List entry) associated with the monthly loan payments to ensure they now transfer Principal to the loan account register and not to a Category.
